Using the Juno spacecraft, NASA will take its closest-ever photos of the giant storm on Monday.

Business Insider simulated what the best single-frame image might look like.

Jupiter's Great Red Spot is about twice as wide as Earth and has tumbled in the planet's atmosphere for at least 350 years.

Despite astronomers' long-standing fascination with this tempest, however, it's mysterious: It's hundreds of millions of miles away, and only a handful of spacecraft have taken detailed images of it.

That will change on Monday, when the space agency's Juno probe will fly within a cosmic breath of the Great Red Spot and take its closest-ever images of the superstorm. The flyby is anticipated to occur around 10:06 p.m.

Candice Hansen, a senior scientist at the Planetary Science Institute, told Business Insider in an email that "this will not be the only flyover of the Great Red Spot planned" for Juno's orbits, but it was the closest.

How Juno will photograph the Great Red Spot

Juno, a robot the size of a basketball court, settled into orbit around Jupiter on July 4, 2016.

But Juno has yet to take close-up photos of the Great Red Spot because Jupiter rotates rapidly, about once every 10 Earth hours. The probe's visits are also fast and infrequent — about every 53.5 days — to prevent it from getting too much exposure to the planet's electronics-damaging radiation.

The robot's main camera, called JunoCam, is expected to beam back new images of the Great Red Spot around Friday, Scott Bolton, a planetary scientist at the Southwest Research Institute and the Juno mission's leader, said in an email to Business Insider.

Scientists like Bolton and Hansen are eagerly looking forward to seeing the unprecedented data.

"Juno and her cloud-penetrating science instruments will dive in to see how deep the roots of this storm go and help us understand how this giant storm works and what makes it so special," Bolton said in a NASA statement.

However, taking photos of the Great Red Spot isn't straightforward. Hansen explained that Juno would fly too close to the storm — about 5,600 miles above it — to capture the whole thing in one view at that point.

Making the task even more challenging, the probe will zoom by at 34 miles per second
. That's speedy enough to traverse the continental US in a little more than a minute.

As a result, JunoCam will strafe the planet with a series of images.

Hansen said the eastern and western edges of the Great Red Spot would be out of view and the northern and southern regions would be "foreshortened due to the viewing angle close to the top of the storm."

This illustration, created by Business Insider based on an image provided by Hansen, shows approximately what JunoCam will see (center) and what it won't (in red) during its flyby.

As Juno zips away from the planet and into deep space, more-distant images should reveal the entire storm — though not in as much detail.

"The closest, most detailed image that JunoCam will return of the Great Red Spot is expected to show more than half" of the storm, Hansen said.

That single photo would capture a similar level of detail as the JunoCam image below, of Jupiter's wandering Little Red Spot.

The much-larger Great Red Spot, however, should fill most of the frame with its eastern and western limbs cropped out.

To get a sense of what the actual photo might look like, we cropped a true-color image of the Great Red Spot, taken in 1996 by the Galileo probe, to match up to JunoCam's view. The new spacecraft's photo is expected to show much more and better detail, however.

Once all of JunoCam's raw photo data is verified, processed into full color, and stitched as a giant mosaic image of the probe's flyby, it will be unrivaled in history.

"The first report of a feature on Jupiter which could be the Great Red Spot was about 350 years ago, not long after the first telescopic observations from Galileo," Bolton told Business Insider. "It is possible the feature has existed considerably longer but there are no recorded observations to provide evidence."

NASA's Juno probe won't fly endlessly around the gas giant. The space agency expects to destroy Juno in 2018 or 2019 by plunging it into the seemingly bottomless, noxious clouds of Jupiter. The goal is to keep Juno from disrupting any aliens — microbial or otherwise — that might live in hidden oceans of water below the icy shells of Jupiter's moons Europa and Ganymede.
